Required hardware configurations

Hi,

I'm planning to introduce cacti to monitor gradually our customer hosts. At the end, the number of hosts should be roughly 200. On each host, we can consider 10 items to monitor (4 network interfaces, cpu and memory usages, disk spaces). The server running cacti will be dedicated, with no limit of bandwidth.
So I would like to have some feedback from users in order to dimension correctly the server.

Regards,
Nicolas Olivier

There are some customers with over 2000 hosts polling over 13000 snmp OID's in about 100 seconds on Win32 using the current version of Cacti.

Thanks. It makes me think that I forgot to say that the server will be under GNU/Linux.
Apparently, cacti runs well, even with a lot of hosts and items, but considering hardware, what is your configuration.

For the big one above it's a dual 3.0Ghz P4 w/Hyper Threading.

Ok, thanks a lot.
And what about memory and hardware disk ?

HD is really up to you, how long and how detailed you want to keep. storing LOTS of data puts it up at 5 megs/rrd, so that will put you around 11 gigs... (basically any computer you buy today will handle cacti fairly easily) (IIRC, default settings give you rrd files under 1 megabyte)

the more memory the better, as mysql loves to have more to cache stuff. 1 gig is a good starting point, 2 gigs is better.

Ok, thank you very much.

I want to poll 1000 nodes every 15 minutes with only one interface per node.
What do you think about this hardware configuration ?

Two P4 3 Ghz, 2 Go RAM, 80 Go HD ?
